ARCHIBALD S. B. LITTLE, OF ST. LOUIS, MISSOURI.

BENCH-GOVERNOR.

[ all whom it may concern:

Be it known that I, ARGI-IIBALD S. B. LITTLE, a subject of the King ofGreat Britain, residing at St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Bench- Governors, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention has relation to improvements in bench-governors formaintaining equilibrium between the retortmain of a gas producer orretort and the main leading from the governor to the pump by which thegas is pumped from such producer or retort.

It consists in the novel details of construction more fully set forth inthe specification and pointed out in the claims.

In the drawings, the figure represents a combined vertical section andelevation of my invention.

The object of the present invention is to 1)1'O"1Cl6 a sensitivegovernor which shall maintain a constant equilibrium between thegas-main and the main leading from the governor to the pump, thegovernor being eminently adapted for use in connection with producergas, coal gas and the like, although not necessarily restricted thereto.

Its advantages will be clearly apparent from a detailed description ofthe invention which is as follows:

Referring to the drawing C, represents an annular sealing tank closed atthe bottom between its inner and outer concentric walls a arespectively, for holding a quantity of water (the water level beingindicated by dotted line w). Over the inner wall a is passed a bell orgas holder 1, the said bell being suspended from chains or cables 2passing over sheaves 3, 3 at the tops of the standards or posts a, 4Lbolted to the upper flange 5 of the wall a, the outer ends of the cableshaving secured thereto balance weights WV, V. The bell is guided in itsmovements and the friction considerably reduced by the rollers 6, 6bearing against the inner surface of the wall a, and by rollers 7, 7mounted on brackets 8, 8 carried by the bell, and bearing against theribs or tracks 9, 9 formed with the standards 4-. Bolted to the upperflange 10 of the wall a is a spider 11 through the center of whichloosely passes a stem or rod 12 the upper end of which is coupled to theroof of the bell by a ball and socket joint 13 which allows theSpecification of Letters Patent.

rod a free movement in any direction, permitting the same to always hangtruly ver- .tically under all conditions. The lower end of the stem 12is connected to a cross rib r of a cylindrical valve 14 which passesthrough the chamber 15 of a hollow base or casting 16 coupled to themain 17 leading from the retort (not shown), the valve being guided inits movements by the upper and lower walls of the chamber 15 throughwhich it passes. bottom wall of the chamber 15 into the chamber 0rcompartment 18 of the casting referred to, into which compartment 18 theis first discharged. The mouth 19 of the chamber 15 is substantiallyopposite the compartment 18, and communicates directly with the main 20leading to the pump, (not shown). The valve 14 is provided with a seriesof peripheral passages or ports 21 of substantially uniform areaterminating in upwardly tapering extensions 21, the extensions being inthe main above the partition wall between the compartments 15 and 18,and the ports 21 being in the main within the compartment 18, whichfirst receives the gas coming from the retort. The tank 0 is providedwith a drain cock cZ as is well understood in the art.

The operation of the governor may be clescribed as follows: As the gaspasses from the retort into the compartment 18 of the base or casting 16it passes through the tapering extensions 21 of the ports 21 into thechamber 15 thence out through the mouth 19 into the pump main 20, thegas likewise accumulating under the bell or float 1. Should theevolution of gas from the gas main 17 become excessive the increasedpressure resulting therefrom will raise the float or bell 1 and thevalve 14 suspended from it, bringing the ports 21 opposite the chamberor compartment 15 when the inrush of the gas through these ports ofcamparatively greater area and capacity will afford instant relief byentering the compartment 15 whence the gas is pumped through the mouth19 into the pump main 20. On the other hand should the evolution of thegas from the retort become reduced, the bell will fall and bring thetapering extensions 21 into play which as the bell continues to fallwill gradually reduce the flow to the compartment 15 and hence to thepump main, and again equilibrium is established, that is to say, theflow of gas into the pump main will always be The valve projects throughthe' draft on the fuel charge shall be practically constant.

Having described my invention what 11 claim is 1. A as overnor com)risin a sealin b c t: m

tank, a bell or float mounted therein, a base forthe support'of the tankprovided with superposed chambers or compartments separated by apartition wall, the bottom chamber leading to a source of gas-supply andthe upper chamber to a point of consumption, and a hollow valve havingperipheral ports composed of substantially constant and reducing areasoperating through the partition between the chambers, the top Wall ofthe upper chamber serving as an additional guide for the valve.

2. A gas governor comprising an annular sealing tank, a bell or floatmounted between the concentric walls thereof, a base beneath the tankprovided with intercomiminicating' superposed chambers separated by apartition wall, the bottom chamber leading to a source of gas supply andthe upper chamber to a point of consumption, and a hollow posedintercommunicating chambers leading respectively to a gas retort main,and to-a pump main, a hollow valve playing across the partition betweenthe chambers aforesaid and provided with peripheral longitudinallydisposed ports of substantially constant area terminating in taperingextensions for establishing communication between the chambersaforesaid, and a stem having a ball and socket joint connection with thebell for connecting the latter to the valve, the top wall of the upperchamber serving as an additional guide for the valve.

In testimony whereof I afiix my signature,

in presence of two witnesses. V
